 * @MPTCP_EVENT_UNSPEC: unused event
 * @MPTCP_EVENT_CREATED: token, family, saddr4 | saddr6, daddr4 | daddr6,
 *   sport, dport A new MPTCP connection has been created. It is the good time
 *   to allocate memory and send ADD_ADDR if needed. Depending on the
 *   traffic-patterns it can take a long time until the MPTCP_EVENT_ESTABLISHED
 *   is sent.
 * @MPTCP_EVENT_ESTABLISHED: token, family, saddr4 | saddr6, daddr4 | daddr6,
 *   sport, dport A MPTCP connection is established (can start new subflows).
 * @MPTCP_EVENT_CLOSED: token A MPTCP connection has stopped.
 * @MPTCP_EVENT_ANNOUNCED: token, rem_id, family, daddr4 | daddr6 [, dport] A
 *   new address has been announced by the peer.
 * @MPTCP_EVENT_REMOVED: token, rem_id An address has been lost by the peer.
 * @MPTCP_EVENT_SUB_ESTABLISHED: token, family, loc_id, rem_id, saddr4 |
 *   saddr6, daddr4 | daddr6, sport, dport, backup, if_idx [, error] A new
 *   subflow has been established. 'error' should not be set.
 * @MPTCP_EVENT_SUB_CLOSED: token, family, loc_id, rem_id, saddr4 | saddr6,
 *   daddr4 | daddr6, sport, dport, backup, if_idx [, error] A subflow has been
 *   closed. An error (copy of sk_err) could be set if an error has been
 *   detected for this subflow.
 * @MPTCP_EVENT_SUB_PRIORITY: token, family, loc_id, rem_id, saddr4 | saddr6,
 *   daddr4 | daddr6, sport, dport, backup, if_idx [, error] The priority of a
 *   subflow has changed. 'error' should not be set.
 * @MPTCP_EVENT_LISTENER_CREATED: family, sport, saddr4 | saddr6 A new PM
 *   listener is created.
 * @MPTCP_EVENT_LISTENER_CLOSED: family, sport, saddr4 | saddr6 A PM listener
 *   is closed.
